Erupt
From your mouth comes a cross, some flowers, and shellfish. It all erupts from your mouth!
Imagine these three things coming out of your mouth not one at a time, but all together like an eruption. Perhaps you're laying on your back, and they burst out of your mouth.

When do inanimate objects erupt from your mouth? Mostly when you're having fun (ふん).
It's really inconvenient that things erupt from your mouth whenever you're having fun. Makes it hard to have fun. Fun fact: when you see 賁 in a kanji, the reading is probably going to be ふん.
